The data place most of the diversification of psittaciformes around 40 Mya, after the separation of Australia from West Antarctica and South America. [ 2 ] [ 4 ] Divergence of the Psittacidae from the ancestral parrots resulted from a common radiation event from what was then West Antarctica into South America, then Africa, via late Cretaceous ...
Parrots (Psittaciformes), also known as psittacines (/ ˈ s ɪ t ə s aɪ n z /), [1] [2] are birds with a strong curved beak, upright stance, and clawed feet. [ a ] They are classified in four families that contain roughly 410 species in 101 genera , found mostly in tropical and subtropical regions.
Described by French naturalist Anselme Gaëtan Desmarest in 1826, [2] the genus Calyptorhynchus has two species of cockatoos. They are all mostly black in colour, and the taxa may be differentiated partly by size and partly by small areas of red, grey, and yellow plumage, especially in the tail feathers.
The parrot order, Psittaciformes, is a tangle of genera, many containing only one species. Parrots include about 353 species—generally grouped into two families - the Cacatuidae or cockatoos, and the Psittacidae or true parrots.

Psittacopasseres is a taxon of birds consisting of the Passeriformes (passerines, a large group of perching birds) and Psittaciformes (). [3] Per Ericson and colleagues, in analysing genomic DNA, revealed a lineage comprising passerines, psittacines and Falconiformes. [4]
The genus was defined by French naturalist René-Primevère Lesson in 1831. The name Micropsitta is derived from the Greek mikros meaning small and psitta for parrot. [5] The pygmy parrots consist of six species and several subspecies: [6] Genus: Micropsitta Lesson 1831 (pygmy parrots)
